By introducing the characteristics of 1 system aluminum alloy and the characteristics of the melting and casting process, it can be seen that the aluminum foil had high requirements for the hydrogen content and inclusion content of the 1-series aluminum alloy melt, and the contents of Ti、Fe and Si in the aluminum alloy and the relative contents of Fe and Si had great influences on the quality of final aluminum foil.In order to produce high quality aluminum alloy slab and cast-rolling plate for 1 series foil，the control of melting-casting process of 1 system aluminum alloy was discussed briefly from the aspects of raw material quality control，chemical composition control，melting process control，on-line treatment process and casting process.
